Description

Приборы дл  измерени  толщины немагнитного покрыти  на ферромагнитную основу, в которых применен посто нный магнит, прит гиваемый к этой основе, известны.Instruments for measuring the thickness of a non-magnetic coating on a ferromagnetic substrate, in which a permanent magnet is applied, attracted to this substrate are known.

Отличительной особенностью предлагаемого прибора того же тппи  вл етс  установка между посто нным магнитом и покрытием промежуточного элел1ента в виде сердечника (иглы) из м гкого железа. Такое выполнение предлагаемого прибора обеспечивает ослабление вли пп  размагничивани  посто нного магнита на точность измерени .A distinctive feature of the proposed device of the same type is the installation between a permanent magnet and a coating of an intermediate element in the form of a core (needle) of soft iron. Such an embodiment of the device proposed provides a weakening of the effect of demagnetisation of a permanent magnet on the measurement accuracy.

Сменный сердечник 1 (см. схему) из м гкого железа расположен между посто ппым магнитом 2 и немагнитным покрытием 3, нанесенным па ферромагнитную основу 4. Если приближать к сердечнику / посто кный магнит 2, то па некотором рассто нии 7 сила прит лсени  между сердечником и магнитом будет равна сумме прит жени  сердечника к основе 4 и веса сердечника. При дальнейгаем уменьшении рассто ни  У произойдет отрыв сердечника } от поверхности покрыти  3.The replaceable core 1 (see diagram) of soft iron is located between the permanent magnet 2 and the nonmagnetic coating 3 applied to the ferromagnetic base 4. If you approach the core / the permanent magnet 2, then at some distance 7 the force of sunshine between the core and the magnet will be equal to the sum of the attraction of the core to the base 4 and the weight of the core. With a further decrease in distance Y, the core will be separated} from the surface of the coating 3.

Между сердечником 1 и магнитом 2 распололсен контакт 5, обеспечивающий замыкание и размыкание цепи, содержащей сигнальную лампу 6 и источник посто нного тока 7. Момент отрыва сердечника 1 фиксируетс  зажиганием лампы 6.Between the core 1 and the magnet 2 there is a contact 5, which provides a short circuit and an opening of the circuit containing the signal lamp 6 and the direct current source 7. The moment of separation of the core 1 is detected by ignition of the lamp 6.

Каждой толщине покрыти  в момент отрыва соответствует вполне определенное рассто ние Y, которое может быть измерено индикатором.Each coating thickness at the moment of tearing corresponds to a well-defined distance Y, which can be measured by an indicator.

Предмет изобретени Subject invention

Прибор дл  измерени  толщины немагнитного покрыти  на ферромагнитную основу при помощи посто нного магпита, прит гиваемого к этой основе, отличающийс  тем, что, с целью ослаблени  вли ни  размагничивани  посто нного магнита на точность измерени , между ним и покрытием установлен сменный сердечник (игла) из м гкого  A device for measuring the thickness of a non-magnetic coating on a ferromagnetic base using a permanent magnet applied to this substrate, characterized in that, in order to mitigate the effect of demagnetization of a permanent magnet on the measurement accuracy, a replaceable core (needle) of the coating is installed mild

железа с тем, чтобы после приближени  к сердечнику магнита на рассто ние, при котором сила прит л ени  между ними была больше силы прит жени  сердечника к ферромагнитной основе, произошел отрыв сердечника от поверхности покрыти  с одновременным замыканием контакта пепи сигнальной лампы.After approaching the magnet core to the distance at which the force of attraction between them was greater than the force of attraction of the core to the ferromagnetic base, the core was detached from the surface of the coating with the simultaneous closure of the contact of the peep of the signal lamp.
